We found himself in the middle of the Olympic Games fever once again. Top athletes are competing at our highest level and strive for top honors in the fields of their choice.
Most will remember the old rubber-soled plimsolls were traditionally worn in PE lessons throughout most European schools. They are available in any color you like as long as it is black or white.
These have been replaced by air cushions, gel filled capsules with superior technicalperformance. They come in a variety of colors, shapes and forms and buy as much for their appearance as their performance.
Production technology breakthrough enables the development of plimsoll called vulcanization, which is still used today. This process uses heat to meld rubber and cloth together. Sulfur is used throughout the process.
Plimsolls were revolutionary at the time as they offer convenience, are lightweight and allow users to movearound silently. Plimsolls called sneakers and was sold on a large scale in the U.S. in early 1917.
In the four years since the last Olympics in Athens technology has moved on somewhat and has definitely moved on from the days plimsoll.
Trainers and clothing has evolved to be lighter and stronger. But what part has technology had to play in improving performance [http://nike-trainers.com/index.php?option=com_content&task=view&id=21&Itemid=2] ourOlympus?
Trainers and sports shoes have evolved, we have shoes for each event is different and each pair of shoes made from a variety of materials were selected because of their personal property to bring power and flexibility, where it is needed most. Materials such as Kevlar is ten times stronger than leather, leather or canvas that is both thin, stable and low density, foam blown polyurethane which gives an extra layer of padding and shoesthermoplastic polyurethane which make a shoe both strong and ductile.
As technology has evolved scientists have developed new composite materials that work together to produce a better performance than the two or three separate materials.
Different materials offer different properties such as stability, provide resistance to twisting and warping. When weight is applied to material in a period of time it will creep (flatten out and spread).
Some materials usedfor their elastic properties, the ability to flex and bend when force is applied and then retain their original shape when the force is removed. Finally, some materials are selected for their density which can be explained as the amount of matter in an object for each measurement of space, these materials are often used to absorb shock.
Polyurethane is a unique material that offers the elasticity of rubber combined with toughness and durability of metal. Types of flexibilitypolyurethane used to make upholstery, mattresses, earplugs, chemical coatings against specialty adhesives and sealants, and packaging. It also comes with other forms of rigid insulation for buildings, water heaters, transport refrigeration, commercial refrigeration and residential. It is used in the manufacture of sports shoes for lightweight shock absorption as well as the nature of it being a very pliable as well as bending and torsion strength. Kevlar is oneThe most important organic fibers ever developed. The fiber has a remarkable combination of properties that led to its use in a variety of commercial products since its invention in 1970. Of Kevlar fibers include extended chain link molecules produced from poly - paraphenylene terephthalamide. Kevlar provides high strength with low weight, structural strength, low conductivity, high chemical resistance, low thermal shrinkage, excellentpower height cut resistant, flame resistant and self-burning. Really quite flexible!
Spiked running shoes have been around for over 100 years created by the British company at the Reebok in 1890. The pointed shoe was developed out of necessity. The founder of the company enjoyed running and wanted to develop a shoe that would increase their speed.
In 1925 a company now known as Adi Dassler Adidas has created a series of shoes with hand forgedspines. They are offering a variety of shoes for different distances. The company used the most powerful and lightweight materials available in time to make running shoes. Adi Dassler is the brother went on to found the Puma sports shoe company.
The involvement of science and technology in the sports shoe manufacturer experts work of 1970 to conduct research on human running. They also investigated for shock effects body caused by the collision between the foot andground. Their finding helped to develop new, innovative shoe sports.
Their research found three types of running styles:
Neutral:
This is where the runner's heel makes contact with the ground and away legs in a straight line as it moves forward.
Pronation:
This is where the heel hits the ground but this time move the leg sideways as it moves forward. It refers to the inward roll of the foot.
Supenation:
This is where the heel hitsground and the foot rolls abroad.
In modern times, such as porous materials, silicon, air or gel has been added to trainers, these have been used to create cushioning system with modern running shoes.
In 1970 a plastic called 'ethylene vinyl acetate (EVA)' was developed. This document revolutionized the construction of sports shoes. It is made up of tiny air bubbles provide cushion and shock absorption. This document was cast into the shape of injection,which serve as support for the heel.
Nike Air technology, using a gas filled air bag mounted in the sole of the shoe to cushion the impact of running, first appeared in 1979. The shoes are named; Tailwind and advanced technology air-soles had provided a good foundation for further progress based on Nike. Since then, athletic shoes have become increasingly specialized and prices for different shoe developed in accordance to the progress intechnology and value-added features. A number of shoes sold in 1980 even included a pump valve so you can go up or deflate the heel on your shoe as if they were bicycle tires.
Following introduction Nike shoes [http://nike-trainers.com/index.php], a technical breakthrough occurred in 1972 when Bill Bowerman, while research models on waffle iron, was give a great idea - waffle sole. Bowerman then cooked some rubber waffle iron and paste it to yourto the bottom of a shoe, which he later gave to athletes to test. The athletes came back with great reviews and the sneakers had been received on the market. The outsole revolutionary patented running by offering better traction in a lighter weight, more durable shoe.
In 2003 Americans spent an average $ 50 (£ 28) on a pair of sports shoes.
The company sponsors top athletes the most. This means that they are paid to wear an asset of the company's productsin a sporting contest.
Olympics is the biggest sporting event in the world to attract television viewers worldwide. This provides an ideal opportunity for sports companies to get their products seen. Just as athletes are finely grinding sports people, athletes are excellent marketing tool for companies and sports shoes.
Would not it be interesting if all the athletes at the Olympics this year had to wear plimsolls, the only option they can do is color,black or white?
We really want to see Olympic champions then.
